Abstract
•The main aim of the work is focused on the preparation and characterization employing elemental analyses, thermal (TG and DTG), spectral (IR, UV-Visible and 1H NMR) and magnetic measurements of new complexes of polypyridyl derivatives as TPTZ (2,4,6-tri-(2-pyridyl)-1,3,5 triazine) with Cr(III), Mn(II), Pd(II), Ru(III), and Pt(IV) metal ions.
• Detailed thermal analysis for the prepared complexes was performed in the temperature range 30-1000˚C.
• The geometries are suggested for the prepared complexes based on the data evaluated from spectral and magnetic measurements.
• Good information about the geometry of Mn(II) complex confirmed by X-ray crystallography studies.
• In order to assess the influence of the structural properties of the ligands and the type of the metal on thermal behavior of the complexes, the order (n) and the heat of activation (Ea) of the various decomposition stages are determined from the TG and DTG using the Coats-Redfern and Horowitz-Metzger methods.
• The redox behavior and electron transfer properties of Ru(III), Cr(III) and Mn(II) complexes wear investigated by cyclic voltammetry (CV).
